ULTRASOUND DISSECTION IN LAPAROSCOPIC CHO LECYSTECTOMY

An ultrasound dissector especially developed for laparoscopic surgery was used during laparoscopic cholecystectomy on 34 patients. The ultra sound power, the volume of suction and irrigation could be determinted individually at the generator and activated during the operation with a foot pedal. With the dissector it was possible to fragmentate, emul gate and aspirate simultaneously fat tissue as well as infected edemat ous structures. The cystic artery and cystic duct, small vessels, lymp hatic and connective tissue were not damaged. Therefore this system se ems to be excellent for the preparation of Calot's trigonum and blunt dissection of the gallbladder out of its bed, particularly in fatty, a cute or chronic infected tissue. No complications were observed within the peri- and postoperative period.
